This is a quick routine to use before your yoga practice to warm-up your upper body, particularly the wrists, hands and fingers. I find a Power Vinyasa Yoga practice with all the Sun Salutations (Surya Namaskar) and Downward Facing Dog (Adho Mukha Svanasana) to be particularly strong for the shoulders, wrists and hands so it is beneficial to gently warm them up before a class. This would also be a beneficial upper body warm up for other types of exercise.
